Hot domestic water recycling kit for storage with coils and circulating pump
The kit allows to connect the recycling way of the hot domestic water to an instantaneous storage tank with coils in a very simple way. The pre-assembled kit, by means of a stainless steel flexible pipe, makes a counter-current circulation that warms the water along the recycling way.
High performance adjustable thermostatic diverting valves. Its material is yellow brass.

Lowara Ecocirc Pro 15-1/65 circulating pump.
The headloss of the DomvS Circ 1 kit is measured between the points A and B of the hydraulic scheme.
The scald protection function stops automatically the hot water running if the cold water of necessary
mixing is not enough.
Recycling working way:
When the circulating pump starts, the cold water into the recycling loop, flowing through the flexible pipe, comes back warmed towards the gate H of the mixer; the gate C of the mixer is usually closed until when the temperature of the recycling loop is approaching to the one selected on the mixer (this condition rarely occurs). The recycling circulation into the recycling loop is working until the temperature is sufficient.
